This invention-relates oa fly tieFs bobBin-Qr to a device which will facilitate the winding and tying of thread intying flies or artificial fish lures.

obj ect of the invention isto -provid'e=a-bobbin adapted to receive a spoolof thread thefree end or which may be withdrawn fiomthe spool and wherein provision ismade-for imposing a frictional resistance or dragon the spoolso that in the course of tying dies and similarfish lures-th withdrawn thread-"will' be withdrawn under adequate tensionvv to. causethe thread, to be tightly wound or tiedabout the lure.

More specifically anobject-of the invention is to provide a fly tiers bobbin consisting ofan elongated. body one end, of which ispointed and the other end of which is recessed to provide a chamber adapted to receive a spool of thread; the free end of which isled unguided to the'point. Within the recess there is provided means: for adjustably imposing. a resistanceson the spool so as to resist its-rotation and cause the withdrawn portion of the thread to be withdrawn under tension. This resistance may be maintained substantially constant by reason of the adj'ustmerit and is normally adequate to prevent rotation of the spool entirely if the bobbin is merely suspended from the withdrawn portion of the thread. There are many situations in the course of tying flies and similar fish lures wherein .it is desired to temporarily interrupt the tying or winding of the thread and have the wound portion retained under constant tension. Under these circumstances by means of the present construction the bobbin may be merely dropped and allowed to remain suspended from the partially tied fly to maintain the tension and if the weight of the bobbin is insufficient to overcome the resistance to rotation of the spool further unwinding of the spool will not take place.

A further object of the invention is to provide a. fly tiers bobbin which is of relatively simple and durable construction and which can be economically manufactured and which can be convenientiy handled in tying flies.

With the foregoing and other objects in view, which will be made manifest in the following detailed description and specifically pointed out in the appended claims, reference is had to the accompanying drawings for an illustrative embodiment of the invention, wherein:

Figure 1 is a top plan view of the fly tiers bobbin embodying the present invention;

Fig. 2 is a longitudinal vertical section through the same and may be regarded as taken sub- 2-.-Claims.. (or. 242-1140 2 stantiallyupontheline 2'2 upon-Fig. l in the direction indicated; and

Fig. 3 is an end view of? the pointed end of the bobbin.

Referring to the" accompanying drawings wherein similar reference characters designate similar parts throughout, the improved bobbin consists of. an elongated body "1101 generally cylindrical shape having one end' pointed as indicated at l I. and'the other end recessed to provide a chamber lithe-rein. The chamber is.pref'- 'erably arranged co-iaxially with the length of the body. This chamber is designed. to receive a spool. of thread indicated" at S, which conventi'onally has. an axial hole Hlthrough its spool. Theend oftheyrecess or. chamber i2" has a pro; tuberance l3 conically formed. and which. is adaptedto partially. enter the forwardend of the hole H. The. chamber i 2'" is closedby meansof a plugor stopper l4formediofresilient material such as cork or rubber and havinga conical forward end I5 that provides a protuberance adapted to enter the other end of the hole H. The. two protuberances l3 and 15 thus provide centers for supporting, the spool S'IOI rotation within the chamber. However, as the plug or stopper M is formed of "resilient material it supplies a considerable frictional resistance to rotation of the spool. By forcing the plug or stopper l4 inwardly into the chamber i2 this resistance may be increased and may be so great that it is impossible to rotate the spool S. By loosening or backing the plug or stopper out of the chamber this resistance may be decreased so that the spool may be rotated quite readily. In this manner by adjusting the plug in or out of the chamber any desired frictional drag may be applied to the spool to resist its rotation. To facilitate this adjustment the exterior of the plug is made cylindrical or substantially so to enable in and out adjustment without involving a loosening of the plug within the end of the chamber.

In the Walls of the chamber there is formed an aperture [6 through which the thread on the spool may be withdrawn. The pointed end H is somewhat thickened adjacent the point and an inclined bore l'l extends through this thickened portion terminating at one end on the point and at the other end approximately flush with the conically shaped end surface of the bobbin. The withdrawn end of the thread is trained through the aperture l6 and along the exterior of the body and through the inclined bore I! so that the 3 end of the thread is dispensed at the center of the pointed end.

In the course of tying a fly or other fish lure the plug l4 may be so adjusted as to impose only a slight drag on the spool. As the thread is Wound about the lure it is withdrawn from the spool through the opening 16 and passes through the bore IT being dispensed at the point. The bobbin which is thus manipulated can accurately position the thread as it is dispensed from the point around the lure.

In many situations it is desired to interrupt the winding or tying of the thread and under:

such circumstances the bobbin may be allowed to remain suspended from the partially wound-0n thread. The frictional resistance to the rotation of the spool is normally adequate to prevent its continued unwinding even if the bobbin is completely suspended therefrom. Under these cir-H 'cumstances the bobbin may be suspended from the lure by the dispensed. portion of the thread during the period of interruption and the weight of the bobbin will cause a tension to be continuously applied to the wound portion of the thread until winding or tying operations are re- The body of the bobbin may be formed of any 0 suitable material although a synthetic resin plastic is preferred. It will be appreciated that the bobbin is of relatively simple construction and can be advantageously employed in tying flies. Whenever the spool has become exhausted it can be easily and quickly replaced with a new spool and the withdrawn portion of the thread threaded or trained through the aperture 16 and the bore I1.

Various changes may be made in the details of construction without departing from the spirit and scope of the invention as defined by the appended claims.

I claim:

1. A fly tiers bobbin comprising an elongated body having one end pointed and the other end recessed providing a chamber adapted to receive a spool of thread, there being a protuberance in the end of the recess adapted to enter one end of the hole in the spool, and a closure for the recess having a protuberance adapted to enter the other end of the hole in the spool, said closure being formed of resilient material and being adjustable toward and away from the first protuberance whereby variable frictional resistance to rotation of the spool may be applied, and means for leading the withdrawn end of the thread to the pointed end of the body.

2. A fly tier's bobbin comprising an elongated body having one end pointed and the other end recessed providing a chamber adapted to receive 1 a spool of thread, there being a protuberance at REFERENCES CITED The following references are of record in the file of this patent:
